Social Networking: how has it changed your relationships?

I've been having fascinating conversations with people about social networking.

A few weeks ago, I spent the morning with a friend's ex & son. At some point, I heard the ex report to the son that they needed to return home on time because "you and your Mom are going out on a boat or something."

Later that night, I saw photos posted from the boat trip: a bunch of my good friends,including the friend & her son, the get together posted that morning on FB as a spontaneous activity.

I admit. I don't like feeling "left out." 10 years ago (heck, 2 years ago!) I could have a party, include some friends, exclude others, & there would be no splashback. Not now - we have access to who's doing what at almost any time - whether by direct evidence or extrapolation.

So I ask -- how has social networking affected YOUR life?
